Power Steering Fluid Cooler: Description and Operation

OPERATION
The purpose of the power steering fluid cooler is to keep the temperature of the power steering system fluid from rising to a level that would affect the
performance of the power steering system.
The cooler used on this vehicle is referred to as a fluid-to-air type cooler. This means that the air flow across the tubes (and fines surrounding them) of
the cooler is used to extract the heat from the cooler which it has absorbed from the power steering fluid flowing through it. The cooler is placed in the
power steering fluid return line, between the steering gear and the power steering fluid reservoir.
